This is our first official errata that changes the functionality of a card in the game.
In Insula Primalis, the card “Enraged T-Rex” has the following text:
At the end of the Environment turn, this card deals the target with the second highest HP 5 melee damage.
This is now officially changed to:
At the end of the Environment turn, this card deals the target other than itself with the second highest HP 5 melee damage.
